Cleaning Tips: Clean your pre-filters every 2-4 months. Pre-filters are very delicate and care should be used while cleaning them. Do not clean pre-filters in the dishwasher. Tap water from the sink or an outside hose should work fine. Do not whip or shake the pre-filters when drying as this could cause ripping. Always allow the pre-filters to dry before placing them back in the air cleaner. Cells may be washed in the dishwasher or the bath tub. When washing cells in the dishwasher do not use a detergent. Also do not use the drying cycle as this could cause uncleaned materials to be baked into the cell. Always consult your dishwasher owners manual before washing cells.
